Sorry, I’m a bit dumb for this one.

Could someone please explain?

There's no such thing as a 100% efficient "engine". But in this case, since the waste heat is put to use (heating the house), OP thinks there's a loophole.

But, house would also need to be soundproof. Any noise leaking to the outside is lost energy.

Let's allow a rounding error for 99.51% shall we?

[-] 18107@aussie.zone 9 points 11 months ago

Don't tell anyone, but I actually only used 1 significant figure, so anything above 50% will do.

I'm also using the version of significant figures where I work backwards from the answer, otherwise I'd need 95% or higher and that's too difficult.
